Why maintaining your AC System is very important:Heating and A/C systems may break eventually with usage, hose pipes may clog and drip if not serviced, causing reduced efficiency heating and cooling capabilities. Regular maintenance will keep your AC system operating at peak performance!

Indications your A/C system may be having issues:

If your air conditioning blows only slightly cooler air compared to the
exterior air

Air that blows in smells damp, musty, or like mildew and
mold

Your cabin does not warm up in cold weather, or is just a little
warmer than outside

The defroster takes longer than typical to operate,
or does not operate

Your heater or A/C only functions when driving, not
when idling, or quits blowing when the car is stationary

Your heating
system blows cold air, or the air conditioning blows warm air

To have an air conditioning system serviced, repaired, or replaced by experts consider visiting Greg's Auto Service and Repair. You can also call us at 314-428-4000 with any questions relating to your vehicle's air conditioner.

Coolant System FlushA car's air conditioning system contains a coolant which transfers excess heat from one part of the engine and finally loses it through the radiator fins. With time, the a/c coolant becomes old and dirty. The old coolant will negatively impact the system's performance. To make sure the system is working effectively, consider having a regular coolant system flush. A coolant flush is basic maintenance for your car's cooling system. Call 314-428-4000 or visit Greg's Auto Service and Repair in St Louis, MO 63114 for all your coolant system flush and fill needs. Ensure maximum performance from your vehicle's heating and cooling systems today.

BeltsA fan belt, also known as a drive belt, is a belt connecting your car's engine to the front mounted accessories. The fan belt rotates the water pump and engine fan, which maintains a cool environment for the engine and its components. Sooner or later, your vehicle's fan belts will dry out and crack. When you are ready for a replacement you can count on Greg's Auto Service and Repair for all your vehicle's repair needs.

You not only have to get the belts replaced with quality ones but you should have the work done by experts. To have the belts replaced by auto cooling and heating experts - and get your car driving right - visit Greg's Auto Service and Repair today. The mechanics at Greg's Auto Service and Repair will thoroughly inspect your car's belts; replace all worn belts; and adjust the installed belts.

HosesHoses transfer coolant and antifreeze throughout the engine's cooling system (including the radiator). Sooner or later, your vehicle's hoses will dry out and crack. When you are ready for a replacement you can count on Greg's Auto Service and Repair for all your vehicle's repair needs.

You not only have to get the hoses replaced with quality ones but you should have the work done by experts. To have the hoses replaced by auto cooling and heating experts - and get your car driving right - visit Greg's Auto Service and Repair today. The mechanics at Greg's Auto Service and Repair will thoroughly inspect your car's hoses; replace all worn hoses; and adjust the installed hoses.

RadiatorsRadiators are heat exchangers for cooling your car's internal combustion engine. A radiator cools the engine by circulating an engine coolant through the engine block - it then loses the heat to the atmosphere through radiation. A radiator has a set of tubes through which the engine coolant flows. Fins surround these tubes. When the radiator fails, the excess heat produced by the engine could damage the engine components. To prevent this from happening, have your radiator serviced regularly. To have your radiator needs handled by experts, visit Greg's Auto Service and Repair today.

Radiator FlushA radiator is the part of your vehicle that keeps the engine cool and protects it from excessive heating. To be cool, the radiator needs to remain clean - always. With time, sludge, rust and other solid deposits build up inside your car's radiator. These make the cooling system become clogged and less effective. This in effect hurts your vehicle's performance. A regular radiator flush is enough to keep the system in shape. For this reason, make radiator flushing a part of your routine car maintenance schedule. For all your radiator flush needs, call 314-428-4000 or visit Greg's Auto Service and Repair today.

Vehicle Tips

According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect.

Vehicle Tips

The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of coolant should be checked. (A 50/50 mix of anti-freeze and water is usually recommended.)

Vehicle Tips

Never remove the radiator cap until the engine has thoroughly cooled. The tightness and condition of drive belts, clamps and hoses should be checked by a pro.

Vehicle Tips

Change your oil and oil filter as specified in your manual, or more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage or tow a trailer.

Vehicle Tips

Replace other filters (air, fuel, PCV, etc.) as recommended, or more often in dusty conditions. Get engine drivability problems (hard stops, rough idling, stalling, diminished power, etc.) corrected at a good shop.

Vehicle Tips

A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.

Vehicle Tips

Have your tires rotated about every 5,000 miles. Check tire pressures once a month; let the tires cool down first. Don't forget your spare and be sure your jack is in good condition.

Vehicle Tips

Vehicle Tips

Inspect the engine's belts regularly. Look for cracks or missing sections or segments. Worn belts will affect the engine performance.

Vehicle Tips

Have the fuel filter changed every 10,000 miles to prevent rust, dirt and other impurities from entering the fuel system.

Vehicle Tips

Change the transmission fluid and filter every 15,000 to 18,000 miles. This will protect the precision-crafted components of the transmission/transaxle.

Vehicle Tips

Inspect the suspension system regularly. This will extend the life of the vehicle's tires.

What our clients say about us?

Reviews and comments from our satisfied customers

I'm a 28-year-old female professional, who has spent many years as an extremely WARY customer of auto shops. This sense of distrust was a result of a myriad of bad experiences with mechanics who took advantage of my lack of knowledge for cars. HOWEVER, I would HIGHLY RECOMMEND putting your faith in Greg's Auto Service and Repair. This is a remarkably well-run business, operated by an owner who actually cares about his customers - not an ounce of greed in this man's heart. My car was in dire need of good attention, and that's exactly what it got. I'm so thankful I stumbled across his business, and I wouldn't take my car anywhere else after working with Greg and his wife Marsha. What a team! This is a MUST-GO repair shop.

-Sonia H.

Wonderful service. We have had several of family cars repaired at Greg's.
Trust and fast service.

-Wilma S.

I've never met a more honest repair shop. They are fantastic. Fast. Reasonable and they don't try to sell me something I don't need. My friends turn me on to Greg's and I'm really happy they did. If you want to feel safe, looking for a mechanic, then I recommend Greg's Auto.

-David P.

People there are extremely nice! When I walk in or call them you instantly feel like a friend that you've known for a few years. That's how well they treat you, you never feel like just a business opportunity it's more of friendship. Highly recommend you go to them for service if you ever need it.

-Corey H.

I came to know Greg when he was working for another shop. Loved his attitude from that day. Asked for him a few months later, but found that he had opened his own shop. I have had work done on my cars by this new shop for many years now, mostly on stuff too hard to do on my own. And he is honest, stands behind his work, reasonable price, friendly and punctual. He keeps you up to date, and there are no surprises sprung upon you. And I know of others who are his repeat customers for those very reasons. I do not typically go around recommending businesses, but for this one, I will do so. Take your car to him, and I am sure you will be happy. Everybody needs to know a good, honest mechanic.
